ARCH SUPPORT.

Application filed June 24,

My invention relates to arch supports and has special reference to arch supports which may be inserted in the shoe of the wearer tor the aleviation of the condition to be remedied.

The principal object of the present inven tion is to provide a simple, efficient and durable arch support.

A further object is to provide an arch support in which reinforcing springs are used, said springs being detachable for ready replacement when broken or otherwise in ured.

A further object of the present invention is to provide in connection with an arch support an adjustable metatarsal support.

Further objects of the invention will appear from the following detailed description thereof.

In the drawings:

Figure 1 is a top view of an arch support constructed in accordance with this invention.

Figure 2 support.

Figure 3 support.

7 Figure 4 is a. perspective of the bolt and nut.

The numeral 1 indicates a plate which may be constructed of leather. hard rubber or other suitable material. Said plate is adapted to rest inside the shoe of the wearer and is arched upwardly as shown in Figure 3, the rar'cd portion being adapted to rest under the foot arch of the wearer.

Adapted to it on the underside and to be secured to the plate 1 are re-in'lorcing springs 2 and 3 Each of said springs is provided near its ends with slots 4 through which bolts 5 are adapted to pass, the plate 1 being provided with perforations for said bolts. The heads of the bolts 5 are slotted as shown in Figure 1, and the plate is countersunk so that the heads will be flush with the upper surface of the plate. The nuts (3 for bolts 5 are constructed as shown in detail in Figure 4, and as so constructed are provided with a central raised portion 7' of dimension to tit snugly in the slots 4 of the springs 2 and 3 respectively. By reason of is a bottom View of said arch is a longitudinal section of the 1926. Serial No. 118,283.

such construction of the nuts 6 the bolts may be tightened in the nuts and said nuts are securely locked against loosening.

Adapted to be secured to the upper side of the plate 1 is a metatarsal arch support or pad 8, the same being of convex construction as clearly shown in Figure 3. The metatarsal pad 8 is made of material similar to that of the plate 1, and is secured to the plate 1 by means of a bolt. 9 which passes. through a perforation in the pad and through a slot 1() in the plate 1, a nut 11 similar to the nut 6 securing the bolt and thereby the pad to the plate 1. As shown in Figure 3 the upper side of the pad 8 is countersunk for the head of bolt 9 so that the surface of said head is flush with the surface of the pad as shown.

From the foregoing description the nature and advantages of the present invention will be apparent to those skilled in the art to which the same appertains.

As will be seen, an arch supporting plate constructed in accordance with this invention may be pnwided either with one or more of the springs 2 and 3 respectively, either of said springs being omitted where conditions are such as to justi't'y or indicate such treatment. Furthermore, the springs E2 and 3, either or both, may be further reinforced and raised by the provision of additional springs in laminated relation, thus raising the support and rigiditying the same where the foot conditions indicate such treatment. The springs 2 and 3 are also longitudinally adjustable with reference to the plate 1 by reason of the slots 4 therein, so that the proper relation and re-in'l'orcenient may be attained with reference to the specific conditions to be remedied. It will also be seen that the metatarsal support or pad 8 is both longitudinally adjustable with respect to the plate 1 and rotatably adjustable thereon about the pivotal bolt 9. It is thus possible to obtain exactly the required placement of the metatarsal pad to remedy the condition to be treated.

It will be understood, of course, that the springs 2 and 3 may also be given such curvature as is suited to the specific conditions in each case.

Having thus fully described my invention What I claim as new and desire to secure by Letters Patent is:

In an arch support, in combination with a plate provided with countersunk perforations for bolts, a reinitorcing spring for said 'plate, said spring being providedwith slots whereby the same may be secured to said 'plate, screw-headed bolts adapted to pass through said perforations and slots, and 10 nuts for said. bolts, said nuts being provided with raised portions adaptedlo fit bolts and to prevent subsequent loosening thereof.
